SEWER-PIPE.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed August 30. 1906- Serial No. 332.584.

To all whom 'it may concern:

Be it known that I, CARL ESCHENBRENNER, a subject of the German Emperor, and resident of Oberlahnstein, Germany, have invented certain new and useful Improvements in Sewer-Pipes, of which the following 1s a specification.

The present invention relates to a construction of sewer-pipes, which can be used while road making and the like advantageously, and especially Where space for covering a sewer is limited and where earthen-'ware or metallic pipes cannot be laid owingto their high girth. Y

At the present time where pipes cannot be employed for the construction of sewers, bricks or stamped concrete blocks of rectangular shape and iron plates for covering the sewers are used which, owing to thene-l cessity of a continued control of labor during the manufacture of the sewer blocks and laying the blocks down as sewer, is highly disadvantageous.

`The present invention remo'ves the said disadvantages by the essential parts of a sewer being manufactured apart and delivered to the plot as partially ready pieces,

for a sewer, which is then a simple matter to lay the pieces down in the form of a sewer and complete it with a nominal and simple amount of labor.

The drawing shows the object of the in'- vention as follows 1 Y f Figure 1 is a cross section view ofl a complete sewer. Fig. 2 a ground plan, and Fig. 3 a longitudinal section view ofa sewer.

The essential parts referred to are the abutments which consists of angular shaped pieces a having iron toothed ribbons b projecting from one end of their angles which goes to thev horizontal line of a sewer, and the abutments are of such size and construction as shall suit the requirement. The abutdown as sewer atany breadth ,required and the intervening space, between the sides from where the iron toothed ribbons project, filled up with concrete or the like as ',ments so prepared have then only to be laid shall bind theabutments together aided by the said toothed ribbons, and should the breadth of the space between-the abutments be too great suitable pieces of wire-netting d and the like is laid, so that the sewer be- I comes strong, binding, and durable, and lastly thetop of the sewer is covered with any suitable material such as beton plates as shown.

I claim,

In the construction of sewers, the combination of the angular shaped abutment pieces a adapted to build broad and narrow sewers,

the -iron toothed ribbons b projecting from a side of the angles of` the abutment pieces adaptedA to lay in the intervening space breadthwise which are filled up with concrete c and bind and strengthen the sewer, the wire netting d laid in the intervening space lengthwi'sewhich is lled up with the said concrete and the beton plate which is used for covering the sewer, substantially as '70 shown and described.
